Just to clarify - are you referring to the reliability of the T6 engine or the XC70 in general?
The cars when over 150,000k (already ten years old'ish) have failures of electronic components that are usually a $1200+ part then towed to dealer for coding.
The transmission is good and can be updated with some expensive valve controller from America but ultimately an expensive repair when it fails.
Rear Haldex fails in a few ways , just the bearing cost me over $2k to have done with bush on front of diff too.
On an XC the suspension is taller and puts more stress on general wera items more so than non XC.
T6 motor WILL start smoking on declaration like a Mack truck and oil consumption increases, currently mine just went from not bad at all to weekly top up from below the lower line on dipstick.....218,000 KLM. Ive got all the bushes and link rods and suspension mounts to do, very expensive too plus fitting cost.
In reality I bought a 130K km car knowing it needed stuff done but with the engine issue I should have dumped it when Haldex needed done.
It's leaking btw too......
Plus what sounds like a wheel bearing.
Im going to dump the thing for a Mercedes ML500. Sure things go wrong with them but I know it's going to be a better marque to drive than modern Volvo is ,in all ways.
I'll miss the T6 zooooom and fun but I'm tired of low, cramped v60 as well.
